A=`date +%m`


set +A YEAR 0 0 Jan Feb Mar Apr May Jun Jul Ago Sep Oct Nov Dec

if (( ${A} == 1 )); then

Try this:

Code:
#!/usr/bin/ksh

A=$(date +%m)

set -A YEAR 0 0 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

if (( ${A} == 1 )); then
   B=Dec
else
   B=${YEAR[${A}]}
fi
echo ${B}

last -a|nawk -v var="$B" '$0 ~ var{p=1} $0 !~ var && p{exit}p'

Regards

p{exit}p i had troubles to understand this.sorry
thank you

Old 07-16-2008
fi ends the if-else block.

Code:
nawk -v var="$B" '$0 ~ var{p=1} $0 !~ var && p{exit}p'

Code:
$0 ~ var{p=1}

If we find the first var we set the variable p to 1

Code:
$0 !~ var && p{exit}

If the next line don't match the month and p was set: exit.

Code:
p

if p is true (1 in this case) print the line, thus we print the line if we find the first match untill the line that don't match.

Regards
